Glaucoma Q & A

What is glaucoma?

Glaucoma is a collection of related eye diseases that damage your optic nerve. This nerve damage can lead to vision problems and, in some cases, total blindness in one or both eyes.

The optic nerve is a bundle of over a million nerve fibers that connect your retina to your brain. Your optic nerve needs to remain healthy to ensure optimal vision.

What causes glaucoma?

In many cases, increased pressure in your eye causes glaucoma. Clear fluid in the eye that nourishes cells and tissues travels through your eye and flows into a passageway where it leaves the eye. If you have glaucoma, the fluid is unable to drain efficiently, increasing the pressure that causes nerve damage.

Glaucoma can also emerge as a result of increased blood pressure in the eye. The level of pressure of either eye fluid or blood before nerve damage occurs varies from person to person. Through regular vision screenings, your doctor determines how much pressure your optic nerve can withstand before becoming damaged.

What are the symptoms of glaucoma?

When you first develop glaucoma, you may not experience any symptoms. Glaucoma is not painful, but eventually, you may begin to lose your peripheral vision. If glaucoma remains untreated, tunnel vision may occur, and eventually, you begin to lose your vision entirely.

How is glaucoma diagnosed?

Dr. Ruiz performs a series of tests to diagnose glaucoma. These tests include:

  • Acuity test: using an eye chart, your doctor determines how well you can see at various distances
  • Field test: measures your peripheral vision
  • Dilation exam: your doctor places eyedrops in your eyes, then uses a specialized lens to examine your optic nerve and retina for damage
  • Tonometry: measures pressure inside your eye
  • Pachymetry: measures the thickness of your cornea using an ultrasonic wave instrument

How is glaucoma treated?

Early detection of glaucoma is essential to receiving successful treatment. Your doctor may recommend one or more of the following glaucoma treatments:  

  • Medications
  • Laser treatments
  • Surgery
